The zero bias anomaly (ZBA) of the tunnel conductivity are investigated in the Al/δ−GaAs tunnel structure with 2D electron concentration in δ-layer to be equal to 3.6∗10 cm−2. We find that the dip (ZBA) in the tunnel density of states near the Fermi level EF reveals logarithmic dependence on the energy ε in the range kT < ε< h̄/τ . Here ε is the energy relative to EF and τ is the elastic relaxat...

Introduction: The use of a simple tissue analog material in the fabrication of medical computed tomography (CT) imaging phantoms has great potential to help researchers. The purpose of the present study is to develop new gel tissue-equivalent materials and determine whether their CT numbers and relative electron densities vary in CT images obtained by scans at different energie...

Evolution of one-dimensional electron system under high-energy-density (HED) conditions is investigated, using the principle of least-action and variational method. In a single-mode modulation model, the amplitude and spatial wavelength of the modulation are chosen to be general coordinates. Equations of motion are derived by considering energy conservation and force balance. Numerical results ...
